Guess I'm a Rationalist Now

Summary

A week ago I attended LessOnline, a rationalist blogging conference featuring many people I’ve known for years—Scott Alexander, Eliezer Yudkowsky, Zvi Mowshowitz, Sarah Constantin, Carl Feynman—as well as people I’ve known only online and was delighted to meet in person, like Joe Carlsmith and Jacob Falkovich and Daniel Reeves. The conference was at Lighthaven, a bewildering maze of passageways, meeting-rooms, sleeping quarters, gardens, and vines off Telegraph Avenue in Berkeley, which has recently emerged as the nerd Shangri-La, or Galt’s Gulch, or Shire, or whatever. I did two events at this year’s LessOnline: a conversation with Nate Soares about the Orthogonality Thesis, and an ask-me-anything session about quantum computing and theoretical computer science (no new ground there for regular consumers of my content). What I’ll remember most from LessOnline is not the sessions, mine or others’, but the unending conversation among hundreds of people all over the grounds, which took place in parallel with the sessions and before and after them, from morning till night (and through the night, apparently, though I’ve gotten too old for that). It felt like a single conversational archipelago, the largest in which I’ve ever taken part, and the conference’s real point.

Within the conversational blob, just making my way from one building to another could take hours. My mean free path was approximately five feet, before someone would notice my nametag and stop me with a question. Here was my favorite opener: “You’re Scott Aaronson?! The quantum physicist who’s always getting into arguments on the Internet, and who’s essentially always right, but who sustains an unreasonable amount of psychic damage in the process?” “Yes,” I replied, not bothering to correct the...
